Tsunami 1 r \ r -, 240V MiTlMlNG LOOP NM ADJUST MON Om 0 0 0 PHOTODIODE PHOTODIODE REF REF REF- 8 80 MHz TO HEAD OUT IN IN DUT OUT \ / L Figure 8-3: Model 3930 Electronics Module Rear Panel Controls and Connections EXT TIMING ADJUST connector-provides connection for an external error input signal (supplied by user). Input impedance is 20 kQ. Signal sensitivity is approximately 7.5 mV/,. This signal is summed with the signal from the coarse and fine TIMING controls (Figure 8-4). LOOP MONitor connector-provides a buffered feedback signal for monitoring on an oscilloscope or volt meter. The best system performance is achieved when the laser is adjusted for the smallest output signal. Output impedance is 1 kQ. Signal sensitivity is approximately 100 mV/,. Output voltage range is approximately f 15 V. Ann OUT connector-provides a fixed, buffered, 10 Hz triangle wave from the internal sweep generator for driving the horizontal sweep on an oscilloscope. The signal is present even when the sweep generator is not selected on the front panel. Output impedance is 1 kQ. PHOTODIODE OUT connector-provides a buffered Tsunami laser photodiode output signal for monitoring on an oscilloscope. Output impedance is 50 Q at -10 dBm for a sine wave. dBm is dF3 with respect to one rnilliwatt: I - To convert to watts: dbm watts = .001 . lom To convert to volts, peak-to-peak: voltspp = 2 . fi - PHOTODIODE IN connector-attaches to the LTC PD photodiode output connectors on the Tsunami laser input bezel. This feedback signal is used by the Lok-to-Clock system to lock the Tsunami cavity to a set frequency. Input impedance is 50 Q at -10 dBm for a sine wave. ', d
